My invention relates to an improvement in linotype-machines; and it consists in devices connected with the ower mechanism and adapted to operate t vator. 7 i v i 'I' will now describe my invention sothat others skilled in the art'may manufacture and use the same. y i

'In the drawings, 2 represents the keyboardshaft, which I employ as the power-shaft of my improved mechanisnn Keyed to the end of the shaft 2 is the gear-wheel 3, and fitting on the keyboard rubber-roll-shaft bracket is abracket 4, which is secured to the collar of the rubber-roll-shaft bracket by means of a split hub or yoke 5. T Extending through the bracket 4 on a line parallel to the shaft 2 is a shaft 6, which is a gear-wheel 7, which meshes with the gear-wheel 3. The gear-wheel 7 is pre vented from moving longitudinally on the shaft 6 by means of a hub 8 and a screw 9, projecting through the hub and into an an nular groove 10 in the shaft 6.

Mounted loosely on'the shaft 6 is a pinion 11, having a hub 12, which is j ournaled in the arm 4 of the bracket 4 and is prevented from moving longitudinally with the shaft 6 by means of a screw 13 passing through the journal 4 into an annular groove 14 in the hub 12.

On the outer face otthc gear-wheel 7 and the inner face of the pinion 11 is a clutch 15 mast For? maowme lhEs-oF {MA I; s ci i ication of ilet t "Application file drnhaijj lsqf Q the; tee 5f mania earths; be

Thus thr-v trigger-arm keeps the shaft 6 from returning to i:.-- normalposition after the pin 29 has passed the end of the spring 16 to allow TIC i that the end of the rack is'niutilated, the

- is of lessv weigh of the assembling elevator, the pinion rotatlever 2 t withdraws the. trigger 20, allox'ving the spr1ng16 to unite the parts of the clutch I the rack and causes it to mesh properly with shaft. This movement of the shaft 6 separates the parts of the clutch 15. releasing the pinion 11 from the gear-wheel 7 and permitting the rack '25 to descend under the weight ing idly on the shaft 6. It will be noticed teeth being removed, so that when the rack reaches the extent of the desired upward movement the pinion has no power to carry it farther, and it remains at this point until released by the action of the pin 29. When it is desired to again raise the assemblingelevator, the linotype operator by touching either of the keys 23 23 or pressing the knee- 15, which causes the elevator .to ascend in i themanner already described. Extending through the journal-casting 4' is an ajdusting-screw 31, which bears against the back of the pinion -1 1.

In order to prevent the assembling-elevator from descending too rapidly, I employ a counterbalancing-weight 32, the cord 33 from whichpasses up a pulley 34, which is journaled on the frame of'the machine, the other end of the cord being secured to the 1 assembling-elevator. The counterweight 32 t t than the weight of the elevator, and when the elevator-rack is released, as already described, and the elevator descends the weight 32 acts'to lessen its speed.

The advantages of my invention result from the construction which enables the elevatorto be raised by the mere touching of a key or; lever, thus obviating the time and manual power which have heretofore been required. i IIaving thus described my invention, what i I claim, and desire to secure by Letters Pa-t ent, is

1. In a linotype-machine, a shaft in com- 1 munication with the power mechanism of the machine, a pinion connected with said shaft, 1 a clutch and a rack extending from the asl power mechanism board and provided with a key,

sembling-elevator and gearing with the pinion; substantially as specified.

2-. In a linotype-machine, the combination of the assembling-elevator, arack connected therewith, a pinion mounted on a reciprocat ing shaft, a clutch by means of which the of the linotype-machine may be thrown in and out of connection w1th the pinion, a trigger by means of which the.

clutch is held in its separated position and a device connected with the line-delivery lever adapted to throw the parts of the clutch out of connection with each other; substantially as specified.

3. In a Linotype-machine the combinationof an assembling-elevator, a rack connected therewith, a plnlon mounted on a reciprocatmg shaft, a clutch by means of which the l power mechanism of the linotype-machine may be thrown in and out of connection with the pinion, a trigger by means of which the clutch is held in its separated position, a lever extending from the trigger to the keyand a device connected. with the line-delivery lever and adapted to throw the parts of the clutch out of connection with each other; substantially as specified. w

4. In a linotypemachine,-the combination of an assembling-elevator, a rack and pinion for raising the elevator, power mechanism for driving the pinion, a clutch by means of which the power mechanism may be thrown in or out of connection with the pinion, a trigger by means of which in its separated position, a lever extending from the'trigger to a point within reach of the operator, and a device connected with the line-delivery the parts of the clutch out of connection with each other; lsubstantially as specified.
